Problem encounter which using Social Zimlet

I have successfully create account of twitter in social zimlet but can not create account of facebook. I always returned this message by facebook as follow.

"An error may have occurred as part of the login process. You can close this window and try returning to the application, though it may ask you to login again. This is likely due to a bug in the application."

I wish to see if the social zimlet support also 6.0.9 and any solution for this problem? thanks
